a software shutdown can be triggered in
firmware by setting the CCPxASE bit to a
‘1’. The auto-restart feature tracks the
active status of a shutdown caused by a
comparator output or INT pin event only
so, if it is enabled at this time. It will imme-
diately clear this bit and restart the ECCP
module at the beginning of the next PWM
period.
